Isolation and structural and optical characterization of the C-2y 1,2-naphthalocyanine isomer
The C-2v isomer of Co(1,2-Nc-C-2v) (1,2-Nc = 1,2-naphthalocyaninato) has been isolated by fractional crystallization of the crude mixture of four isomers (C-4h, C-s, C-2v, D-2h), and its crystal structure, electronic absorption, and magnetic circular dichromism have been discussed.
